Description

DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention relates to photosensitive materials. More specifically, a photosensitive silver halide is used as a photosensor, and by utilizing the image-like latent image formed on the silver halide when irradiated with actinic radiation, a polymer compound is detected by heating or uniform exposure. The present invention relates to a photosensitive material that is formed and immobilizes coexisting dyes or dye-forming substances.

"Prior art" As a prior art similar to the present invention C2,
a3gSt (US Pat. No. 327?KK4). Here, a photosensitive material containing many fluid droplets that become non-flowing when exposed to light is imagewise exposed to light, superimposed on the receiver, and a pressure applied across the entire surface. , discloses a method of transferring an image corresponding to the upper C2 exposure to this image.

This prior art has low sensitivity to light and is noticeably lacking in sensitivity to special C2 green light and red C2 light. Well, if you try to increase this sensitivity, it has the disadvantage of decreasing storage stability.

- In the image forming method using silver halide as a photosensor, various materials other than so-called conventional photographic materials are known. For example, British Patent No. /6≦t
No. Ji discloses a method of directly causing photopolymerization using silver halide as a catalyst, but in this method, it is thought that the product generated by photolysis of silver halide acts as a catalyst for polymerization. Therefore, it is not possible to obtain as high a sensitivity as in the case of reducing silver halide using a conventional method. Belgian Patent No. 3'12H77 l2 develops exposed silver halide grains with an ordinary developer, and then polymerizes the resulting silver image or unreacted silver halide as a catalyst to form a polymer compound. A method is disclosed for forming an image-like image, but in this case f2 requires complicated operations. Furthermore, special public Sho Geta-7/lda No. 9, same 9t? −

≦No. 32, same evening ♂-7≦RI/DA No. 3 states that when exposed silver halide is developed using a reducing agent, the reducing agent is oxidized and at the same time the coexisting vinyl compound is polymerized. A method for forming an image-wise polymeric material is disclosed, but this method uses a liquid and requires a subsequent development step.

There are various known image forming methods that use silver halide as an original sensor, but all of them offer high sensitivity and disadvantages such as requiring complicated development processing steps. doing.

On the other hand, Tokugansho! In Patent No. 19/333 (2), a simple method of forming images by thermal development I!+1 is proposed.

``Problems to be Solved by the Invention'' The present invention has (1) high sensitivity to 2 lights (necessarily 9 + 2), high green light and red light (sensitivity to 2), and (2) excellent stability over time. The object of the present invention is to provide a photosensitive material that (3) allows image formation with simple operations.

``Means for Solving the Problems'' The present invention comprises on a support at least a photosensitive silver halide, a reducing agent, a polymerizable compound and a color image-forming substance,
The photosensitive material is characterized in that at least the polymerizable compound and the color image forming substance among these are present in the same oil cylinder.

The recording material containing two phases of the present invention C uses photosensitive silver halide as a photosensor, and latent image nuclei of silver halide generated from image exposure≦2 act as a catalyst to carry out an oxidation-reduction reaction between a silver salt and a reducing agent. The radical intermediate generated in the process is either carried out as an initiator for the polymerization reaction, or the radical generated by reacting this product with another compound after a redox reaction between the reducing agent and the silver salt. A one reaction reaction is carried out using as an initiator. This series of reactions heats
Furthermore, it could not be expected from conventional knowledge that the uniform exposure C2 direction would be significantly accelerated. The emergence of a body is a completely new theoretical finding.

The photosensitive material of the present invention is characterized in that a substantial polymerization reaction does not occur by image exposure alone.

In the present invention, depending on the type of photosensitive silver halide used, it is possible to produce a polymer compound corresponding to both exposed and unexposed areas. In the fixed part (oil droplets) where the polymer compound is produced, in the part where it is not produced (oil@) 1-
In comparison, the pressure resistance is increased, and as a result, a color image can be formed using a color image-forming substance by transferring a portion where a polymer compound is not formed to the image-receiving material C by applying pressure. Therefore, in the present invention, depending on the type of photosensitive silver halide used or the color image forming process C2 adopted, both negative and positive images can be freely created for the original image C2, and in some cases both negative and positive images can be created. It is also possible to create two images at the same time.

For example, if you want to obtain a color image by transferring a part where no polymer compound is formed, you can use a normal negative silver halide emulsion to obtain a positive image by pairing the original image with one another. , U.S. patent *2 for forming a negative image. Evening 92.2j'0, same 3. ．． 20t, No. 313, No. 3,367.27♂, No. 3. The internal image silver halide emulsion as described in v%t7,927 C2 was combined with the surface image silver halide emulsion as described in -f7tf National Security Council, Data A, No. 372 (-) and the internal me halide emulsion as described in Mixtures with bride emulsions can be used.

In the present invention, when obtaining a wide range of colors in the chromaticity diagram using the three primary colors of yellow, magenta, and cyan in the subtractive color method, the light-sensitive material is a halogenated material that is sensitive to different color ranges in at least three glazes. It is necessary to have a silver emulsion.

Typical combinations of at least three light-sensitive silver halide emulsions having sensitivity in the vector region having different 1/kl from each other include a combination of a blue-sensitive emulsion, a green-sensitive emulsion and a red-sensitive emulsion, a green-sensitive emulsion, Examples include a combination of a red-sensitive emulsion and an infrared-sensitive emulsion, a combination of a W-sensitive emulsion, a green-sensitive emulsion and an infrared-sensitive emulsion, a combination of a blue-sensitive emulsion, a red-sensitive emulsion, and an infrared-sensitive emulsion. Note that the infrared light-sensitive emulsion herein refers to an emulsion that is sensitive to light C2 of 700 nm or more, particularly (near u Onm or more).

For example, when using a combination of a blue-sensitive emulsion, a green-sensitive emulsion, and a red-sensitive emulsion, the blue-sensitive oil droplets become yellow+
1! The green-sensitive oil droplets may contain a magenta image-forming substance, and the red-sensitive oil droplets may contain a cyan image-forming substance.

In this way, it is possible to separate the yellow, magenta, and cyan image-forming materials and include them in the same photosensitive element, and it is possible to separate the image-forming materials of yellow, magenta, and cyan into the same photosensitive element, and this makes it possible to separate the image-forming materials of yellow, magenta, and cyan into the same photosensitive element. !11 images can be formed.

Color images can be created using the above-mentioned known technology! When trying to form , (1) there is no sensitivity to green light and red light, (2) there is low sensitivity to blue light, (3) there is poor stability over time.

All Iji can be solved. Therefore, the photosensitive material of the present invention has a great effect on color image formation.

The following examples can be given as the configurations of the photosensitive element 2 and the image receiving element in the present invention f2. The light-sensitive element referred to herein includes a chemical halogen compound, a chemical agent, a chemical compound, and a color image-forming substance, and among these, at least the chemical compound and the color image-forming substance are the same.

(2) A color image-forming substance is colorless or pale in itself, but develops color when other energy is applied.

The configuration in this case can be considered to be the same as (at and (t)) of fl above, but in either case, a step of applying energy to color the color image forming substance is required. However, if this color development occurs simultaneously at the time of application P8 or exposure or pressure in (1), there is no need to add a special process.
